AvaRegions: Avalanche Problems Across Canadian Mountain Regions

Description Usage Format Note References Examples

Description

Contains dissimilarity matrices across mountain regions in British Columbia and BC for each of the 13 avalanche problems. The extended Dice coefficient was used on problem prevalences in order to compute the dissimilarities. This computation was carried out for each elevation band (alpine, treeline, below treeline) separately.

Usage

1

Format

For each elevation band a list of dissimilarity matrices is provided for the following avalanche problems:

DeepP

Ldry

Loose dry avalanche

Lwet

Loose wet & persistent slab

NoProbs

No avalanche problems

Pers

Persistent slab

PersPlus

Persistent slab plus

Spring

Spring-like

Storm

Storm slab

StormDeepP

Storm & deep persistent slab

StormPers

Storm & persistent slab

StormWind

Storm & wind slab

StormWindPers

Storm, wind, & persistent slab

Wind

Wind slab
